For the first time ever I had to cancel my holidays due to climate change. I was planning on skiing in the first week of January, not gonna happen. It was 14 degrees during the day on 31 Dec. 20 years ago it was unusual not to have snow for Christmas and New Year.
Weather is not climate.
OP could have given a long, complex nuanced statement to appease pedants like "Due to climate change making warm weather and lack of snow in January far more likely than in the past, there was in fact warm weather and lack of snow during my planned trip, so I had to cancel my plans. The odds of this happening without decades of carbon emissions from fossil fuels would have been very unlikely".
Or, you can skip all that excessive cruft which is understood by almost everyone as being implicit and just say due to climate change.
